Evaluating Highly Transient Heat Transfer and Combustion Processes for Application to Advanced Engines and Electronics Cooling
Abstract
We request $196,225 to purchase a MS M1K infrared camera and supporting equipment. What makes this infrared camera unique (and need ed) is its high sampling frequency (up to 40 kHz) and the high frequency filter wheel (near 100 Hz). The unique capabilities of the camera will allow us to perform pioneering research which is significant to the Navy and that is impossible, or challenging at be st, to conduct with other cameras or other measurement techniques. Our expertise in infrared thermography, combustion, and heat tra nsfer, combined with the unique research capabilities enabled by the camera, will enable us to successfully conduct the proposed r esearch and in the process provide transformative educational training for students. The proposed camera will be used to enhance 4 research projects of Naval relevance. Specifically, we will use the camera to help identify sensitivities of ignition of jet fuels to the presence of combustion products (application to afterburners), identify the distribution of jet fuel and combustion produc ts in detonation fronts (application to rotating detonation engines), measure transient heat fluxes of detonation fronts (applicati on to rotating detonation engines), and measure coupled hydrodynamic and thermal profiles for transient condensate nucleation (app lication to reducing form factor for electronics cooling). The former two efforts compliment an existing ONR Young Investigator Pro gram award and an ONR BAA award.Education of students will be strengthened through four avenues using the proposed high speed infr ared camera. Specifically, (1) students will develop expertise with using an infrared camera and applying infrared thermography to identify phenomena, (2) graduate student(s) will have an opportunity to interact with engineers from GE Aviation and GE Global Res earch Center, (3) undergraduate students will be mentored and allowed to perform research using the camera, and (4) the camera wil l be used to help expose students to heat transfer environments wherecoefficients larger than 10 kW/m2K are observed in two-phase c ooling flows. A three-fold approach will be used to transition the knowledge gained from the studies using the camera to benefit t he warfighter. First, we will have an active collaboration with industry partners, GE Aviation and GE Global Research Center (POCs: Dr. Keith McManus and Eric Ruggiero). Second, we will transition the knowledge gained from our studies to the propulsion industry by providing briefings to the major gas turbine engine companies and DoD engineers (e.g., Pratt and Whitney, GE, AFRL). Our third method for benefitting the warfighter is by proving that two-phase immersion cooling is a viable thermal management option for com pact military-grade communication systems.
